annoyed...

i wonder... why don't i just stop caring about people? why don't i just think about what suits me best, instead of trying to be nice and please others? i don't know... but i think i should... it would mean less emotional exposure, less involvement, less disappointment...
my sister booked 4 places to go to a blind dinner... one of them was supposed to be mine... until she decided to invite someone else, and pretended that our conversation about me going to that dinner with her never happend... just as she did last summer... when i offered to go camping with her over the midsummer week and she said she was definitely not going on holiday that week... in the end she went exactly that week and ended up camping on her own cause her two friends she went with were retarded...
this week i was supposed to stay over at a friend's house, cause she was alone... and because we wanted to use the time to catch up a little... then i found out she had invited someone else too... not that i need to be the only one all the time... but it's not that we hang out all the time... and i thought this time was supposed to be for us... she probably thought something different...
and i am not taking it the best way possible...
